The analytical decision for effective electro-magnetic elastic properties of piezo active composites on the basis of decision of stochastic connected boundary-value problem of electro-magnetic elasticity by generalized singular approach of method of periodic components for quasiperiodic random structures of transversal-isotropic composites is received. Numerical analysis for effective factors of electromagnetic connection of layer composite depending on curvature of layers is presented. The composite consist piezoelectric PVF and ferrite layers.
